1、专业八级分类模拟411及答案解析 (总分:160.10,做题时间:90分钟)一、PART READING COMPR(总题数:1,分数:100.00)Section A In this section there are several passages followed by fourteen multiple-choice questions. For each multiple-choice question, there are four suggested answers marked A, B, C and D. Choose the one that you think is t
2、he best answer and mark your answers on ANSWER SHEET TWO. Passage One Driving along South Street, where the Los Angeles sprawl meets sprawling Orange County, you enter and leave Cerritos three times. Although the city is confusingly shaped, it is easy to tell where it begins. Overhead power cables a
3、bruptly disappear and run underground. The grass, watered by innumerable sprinklers, is a brighter shade of green. Indeed, a blind man could tell where the boundary lies. Crossing into Artesia there is a bump, followed by a series of clumsily patched potholes; a few hundred yards later you re-enter
4、Cerritos and the road is smooth again. Cerritos cannot boast a glorious history, old money or natural beauty. Fifty years ago it was a flat area of farmland known as Dairy Valley. These days, its a terribly unremarkable place on the way to Disneyland, says Tom Irish, a property developer. Yet this s
5、mall suburban city of some 55,000 people has become remarkable thanks to superb management and geographical good fortune. It reveals much about why Americas suburbs are so appealing, and how they are changing. Like an increasing number of suburbs, Cerritos is both a bedroom community and an economic
6、 engine. It began to prosper in the early 1970s when it encouraged car dealers to cluster near the motorway that clips its western edge. Fully 27 outfits now trade there, making it the largest such centre in a car-obsessed state. Cerritos also has a shopping mall and a town center, otherwise known a
7、s an office park. As a result, it has far more jobs than working residents. Last year the city collected $ 483 in sales taxes per personmore than the glitzy city of Santa Monica. And it has leased, not sold, its land, so a future stream of money is guaranteed. What goes on inside the offices seems l
8、ess important to locals than what they look like. The city has municipal codes to rival those of notoriously staid Irvine, a planned city in Orange County: dont even think about installing a rotating, blinking or oscillating sign. Sculptures adorn car dealers forecourts. Cerritoss busy library is co
9、vered with titanium; its Wal-Mart is clad in granite. It has an opulent performing arts centre that will host some 140 impeccably populist acts this year. Building work is underway on the local jail, known for good reason as the sheriffs hotel. Although Cerritos has a contract with Los Angeless coun
10、ty sheriff for its policing, it pays for the building and the officers. They have some of the easiest jobs in California. So far this year 53 serious assaults have been recorded, a bit less than one per cop. The city is so peaceful, says Daryl Evans, the police captain, that gang members from nearby
11、 cities occasionally meet there to play basketball, knowing they will not be attacked by rivals. Of course, many American cities have built parks, performing-arts centres and fancy libraries while struggling financially. The key to Cerritoss success may be the timing of its investments. Cities such
12、as Cleveland and Baltimore poured money into museums and other grand projects in the vain hope that they would lure businesses and young, creative folk. Cerritos began by building pipelines and roads, then moved on to business parks, policing and schools (including Californias best high school). Onl
13、y when it was rolling in money did it break out the titanium. Local officials attribute the citys success to fiscal discipline and the ability to follow a long-term plan. That, in turn, is the result of its political culture. Cerritos has a tradition of powerful, long-serving city managers, to whom
14、local politicians frequently defer. As Laura Lee, the mayor, explains, There are many things we, as elected officials, do not understand. Voters, it seems, like this arrangement greatly. In a 2002 poll, an astonishing 96% of residents said they were satisfied with the provision of public services. S
15、uch single-mindedness is particularly striking given the citys diversity. In 1980 whites comprised more than half of the population. These days Asians do. Striving immigrants are cause and consequence of the citys excellent schools, in Cerritos High School, pupils who speak inadequate English score
16、better in mathematics tests than those who speak English fluently. Yet the newcomers have not formed ghettos. The last census showed that whites and Asians were more intermixed in Cerritos than in all but 16 other American cities. Whites were even more mixed-up with blacks and Hispanics. These days
17、Cerritos faces strong competition. Its car mall has inspired imitators; as a result, the value of sales has flattened while the number of vehicles sold seems to be falling. As the city ages, public services will come under increasing strain. Drastic decline is unlikely, but the city may be overtaken
18、though it is almost certain that the places doing the overtaking will be bland, car-oriented and suburban. (此文选自 The Economist)Passage Two In 1751, Swedish botanist Carolus Linnaeus came up with the novel idea of using flowers as clocks. Morning glories open their trumpet-like petals around 10 a. m.
19、 , water lilies at 11 and so on through evening primroses and moonflowers. A full array of these blossoms, planted in a circle, could indicate the time. It was a whimsical notion. But some 250 years later, scientists are seriously interested in the timekeeping mechanisms of nature. Theyre so ubiquit
20、ous, theyre almost a signature of life, says molecular neuroscientist Russell Foster of Imperil College, London. From cockroaches to humans, Foster explores these internal clocks in a fascinating new book, Rhythm of Life, co-authored with British science writer Leon Kreitzman. The author show how th
21、e daily patterns known as circadian rhythms influence far more than our sleep. Heart attacks are more common in the morning. Women tend to go to labor in the evening. Severe asthma prevail at night. Although we may jet across time zones, circadian rhythms rule. The book traces the century-long quest
22、 to unravel their mechanisms, with some starting outcomesincluding the recent discovery that certain genes switch on and off in 24 hour cycles. Even our responses to medicines may depend on when we take them. Nature has devised internal clocks for a simple reason: they aid survival. The early bird r
23、eally does get the work, thanks to a silent wake-up call before dawn. A mimosa plant spreads its fernlike leaves during the day to create the maximum surface area for photosynthesis, then folds them up at night to reduce water-vapor loss. Its not a mere response to light. They do this even when kept
24、 in the dark, says biologist Eugene Maurakis of the Science Museum of Virginia. In humans, the master clock is a tiny clump of cells in the brain called the suprachiasmatic nuclei. The clocks is reset daily by signals from a novel type of photoreceptor in the eye that Foster discovered. The blind re
